Genes affected

PDIA5 (HGNC:24811): (protein disulfide isomerase family A member 5) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, three catalytically active thioredoxin (TRX) domains, a TRX-like domain, and a C-terminal ER-retention sequence. The N-terminal TRX-like domain is the primary binding site for the major ER chaperone calreticulin and possibly other proteins and substrates as well. Alternative splicing results in multiple protein- and non-protein-coding transcript variants. [provided by RefSeq, Dec 2016]

The c.296T>C (p.V99A) alteration is located in exon 4 (coding exon 4) of the PDIA5 gene. This alteration results from a T to C substitution at nucleotide position 296, causing the valine (V) at amino acid position 99 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
